P254F OBD-II: Engine Hood Switch Circuit
P254F Severity
Will P254F go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P254F?
The engine hood has two switches, a hood ajar switch and a hood closed switch. Normally, when one switch is open, the other switch is closed. If both switches are closed or open at the same time, code P254F will be stored and the engine will be prohibited from starting.
